The National Aero-Space Plane Program?A Revolutionary Concept
NASP - The National Aero-Space Plane is a look into the future. The NASP program can be described in a number of ways: technological, programmatic, utilitarian, and conceptual. In order...
Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...
Housing Opportunity or Social Engineering Implementing the Jobs-Housing Relationship?The Town of Wellington Experience
The proposed Town of Wellington project in Palm Beach County, Florida, was planned based on the needs related to the jobs-housing relationship identified in the area. The conditions placed...
Performance Specifications for the Design and Manufacture of Energy Efficient Housing in the 21st Century
This paper reports on work in progress in `Design for Energy Efficiency', one of fifteen task areas of the U.S. Department of Energy sponsored Energy Efficient Industrialized Housing research...
Integrated Software for Transportation Emissions Analysis
As the air pollution problem in the major metropolitan areas of the United States has increased, new interest has emerged for greater accuracy in the estimation of emissions from mobile...
In-Use Emissions with Today's Closed-Loop Systems
Closed-loop emission control systems were adopted by most motor vehicle manufacturers on a wide-spread basis in model year 1981, in order to meet the 1981 and later Federal exhaust emission...
Risk Analysis in Water Resources Engineering: Development and Application
Traditional engineering approaches for evaluating safety and performance in technical projects are usually based on conceptual modeling and the application of engineering standards. Risk...
Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
Extended Kalman Filter-Finite Element for Geotechnical Problems
A parameter identification method has been developed in geotechnical engineering problems, where the extended Kalman filter-weighted local iteration procedure is developed incorporated...
Site-Dependence of Spatial Coherency
The spatial coherency of ground motion from nine dense arrays are analyzed to examine the site-dependence of spatial coherency. The spatial coherencies computed for arrays located on alluvium...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Digital Simulation of Wind Load Effects
The time domain solution of the equations of motion of structures subjected to a stochastic wind field is often obtained by a step-by-step integration approach. The loading is often described...
Comparison of Wind Cross-Spectral Data with Models
Existing analysis procedures for the prediction of long-span bridge response to wind have until recently neglected the horizontal-vertical cross-spectral components of the wind under the...
Non-Gaussian Vortex Induced Aeroelastic Vibrations under Gaussian Wind
The 'lock in' aeroelastic vibration phenomenon observed for random wind excitation is modeled in a way that allows the application of the Slepian model process tool to obtain an approximation...
Some Modeling and Analysis Techniques for Wave Propagation in Random Media
Some mathematical modeling techniques for the problem of wave propagation in randomly imperfect periodic medium are reviewed: multiscale formulation and random evolution modeling. These...
Probabilistic Order of Chaotic Dynamics
A chaotic dynamics system generally turns a deterministic input into a random-like output. Although the response is not directly predictable in the deterministic sense, its probabilistic...
How to Improve Writing Skills
Many papers submitted to ASCE journals are rejected because of poor writing. Moreover, the most common complaint employers have of newly graduated engineers is their lack of writing skills....
Standard Reference Evapotranspiration Calculations: REF-ET
REF-ET is a PC software program for computing standard calculations of reference evapotranspiration (Eto) and associated variables. Computations...
